Unacceptable attitude from a consultant

I have an existing funeral policy with Hollard Life. At inception date i was advised that my premium will stay the same until claims stage. I received an sms from Hollard on the 27 December informing me of increase in premium effective 1 February 2018. I contacted Hollard life call centre to enquire about the sms and to my dismay i encountered a less than impressive service from a consultant by the name of Charity Tlou. I asked Charity to explain what the sms i received was about, he proceeded to talk over me with a rude tone by saying that i cant expect premium to stay constant despite trying to explain the inconsistency at sales stage. Charity was rude and proceed to put me on hold, until i had to put the phone down and call again. I am a paying, loyal customer of Hollard and clearly customer centricity is not a term that your consultant are not fami**** with. The call was made yesterday. I must end of by saying that if you have representatives like Charity in your organisation that speak to customer the way he spoke to me, then Hollard must close its doors.
